Definitions

  • the present invention relates to an improvement in a clamping band to be used to clamp and fix a cylindrical member such as a boot made of an elastic material, to a fixture having a circumferential surface.
  • a clamping band made of band steel has been used to clamp and fix a cylindrical boot or cover to a fixture having a substantially circumferential surface such as a transmission shaft of a vehicle.
  • Various clamping bands have been known conventionally.
  • One example is disclosed in Japanese Patent Appln. Laid-Open No. 63-259207 assigned to the assignee of the present invention.
  • the band is first curved in a loop shape, the opposite ends are over-lapped radially, and then a clamping tool is engaged with tool engagements (holes or projections) at the ends of the band to apply a clamping force tangentially to the ends to reduce a radius of the band, and finally an engaging portion of the inner end and an engaging portion of the outer end are engaged.
  • An engaging pawl formed on the second end, which is radially outer end when the opposite ends are overlapped, is critical. If the engaging pawl is formed at a portion spaced or retracted away from the tip of the second end, the second end may be separated from the outer periphery of the first end and drift radially outerwardly after the clamping.
  • a retaining member is provided at the first end to prevent the drifting outward of the second end.
  • the retaining member comprises a fixed member fixed to the inside of the first end and a pair of arms extending outward therefrom to engage with the second end.
  • tip edge of the second end is exposed along the outer peripheral surface of the first end, a step having the thickness of the second end is formed.
  • surrounding parts may interfere with the step (tip edge) so that the band might be taken off from the boot.
  • the drifting outward of the second end is prevented without providing a retaining member separately from the clamping band and hence without forming a projection on the inner peripheral surface of the inner end.
  • FIG. 1 shows a perspective view of a clamping band according to the present invention, (with a middle portion thereof omitted),
  • FIG. 2 shows a sectional view illustrating a clamped state
  • FIG. 3 shows a plan view of the same.
  • a clamping band 10 comprises a main body 12 made of a steel having a predetermined width.
  • a first (inner) end 14 which is the radially inner end when the band is looped with the ends thereof overlapped, apertures 16, 18 and 20 are formed in sequence as viewed from the tip edge.
  • a tunnel-like projection 28 is formed on the side of the first aperture 16 facing the tip edge (left side in FIG.
  • a temporary clamping pawl (third engaging portion) 22 which extends radially outwardly is formed on the side of the second aperture 18 facing the tip edge
  • a primary clamping pawl (first engaging portion) 24 which extends radially outwardly is formed on the side of the third aperture 20 facing the tip edge
  • a tunnel-like projection 26 is formed on the opposite side.
  • the slot 36 is long enough to permit the fitting of the clamping pawl 22 and the projection 28.
  • the heights (projections) of the clamping pawl 24 and the third clamping pawl 38 are selected substantially equal (about equal to the thickness of the middle portion 12), and the height the t 1 of the pedestal area 32 of the second end 30 as measured from the inner periphery 15 of the first end 14 and the height t 2 of the tunnel-like projection 26 are substantially equal (and approximately as twice large as the thickness of the middle portion 12).
  • the height t 2 may be slightly larger than the height t 1 .
  • the clamping band 10 is looped, the transmission shaft and the boot (both not shown) are surrounded by the middle portion 12 of the clamping band 10, the second end 30 is overlapped on the outer side of the first end 14, and the clamping pawl 22 of the inner end 14 and the clamping pawl 38 of the outer end 30 are engaged. This is called “temporary clamping”.
  • the projection 28 of the inner end 14 fits into the slot 36 of the outer end 30.
  • a pair of clamping force application members of an expansion type clamping tool (not shown) are engaged with the edge 37 (FIG. 2) of the slot 36 and the projection 28, and an expansion force in a tangential direction is applied to the clamping force application members to drive the inner end 14 and the outer end 30 to the directions which increase the overlapped area (in FIG. 2, leftward for the inner end 14 and rightward for the outer end 30).
  • the clamping pawl 38 of the outer end 30 is caused to ride over the clamping pawl 24 of the inner end 14 and is engaged therewith. This is called “final clamping” and is shown in FIG. 2. Under this state, the clamping pawl 22 and the projection 28 of the inner end 14 fit into the slot 36 of the outer end 30.
  • the clamping pawl 38 of the outer end 30 is formed in the vicinity of the the edge and an area ahead thereof (toward the tip edge) is very short. Accordingly, there is no risk that the area ahead of the clamping pawl 38 of the outer end 30 might drift outward from the inner end 14. Thus, the retaining member described earlier need not be provided at the inner end 14, and the inner peripheral surface of the body 12 is made flat so that the closure of the clamped body is enhanced.
  • the pedestal area 32 at the tip of the outer end 30 and the projection 26 of the inner end 14 are positioned at substantially the same height (t 2 ) as measured from the inner peripheral surface 15 of the inner end 14, and there is no step formed therebetween. Accordingly, there is almost no risk that surrounding parts will interfere with the pedestal area 32, because the interval between the clamping pawl 24 and the projection 26 is also selected giving due regard to the distance of the tip edge of pedestal area 32 from the edge of the aperture 34. Since the projection 26 smoothly projects and no corner is formed, there is no risk that it will e broken even if it interferes with the surrounding parts.
